Do:clean up spills immediately.
Acidic substances like sodas, coffee, tomato sauce, fruit juices, and wine will not etch granite like they do marble, but they could potentially stain the surface. Cooking oils may also leave a stain if not wiped up.

Again, granite won’t etch and using coasters on dense and/or properly sealed granite is not an absolute necessity like with marble, but using coasters is just a good practice to protect all surfaces.

Do:Use trivets and hot pads under pots & pans.
You can set a hot pot off the stove and put it directly on granite countertops without a problem. It is possible for granite to suffer heat shock and crack, but very rare. One does not don’t want to put hot pans on any other surface.
